Specification of Letters Patent.

Patented March 10, 1908.

Application filed July 17, 1907. "Serial No. 884,166.

Beit'known that LDrxon E. WASHING- TON, a citizen of the United States, residing at Chicago, in the county of Cook and State of Illinois, have invented certain new and useful Improvementsin Conveyers, of which the following is a specification.

This inventionrelates to im rovements in conveyers more particularly a apted for use in conveyingor transporting beef and the like from one place to another during the different steps of dressing the same, and the primary object of the invention is to provide 1m roved means for preventing the axial rotatlon or twist' of the hanger upon its supporting track due to the swinging movement or twisting of the heavy load, which would tend to displace the hanger.

A further object is to provide an improved endless conveyer adapted to be supported.

adjacent a supporting track upon which latter the hangers travel, the hangers being adapted to engage the conveyer as they move upon the track. a

A further object is to provide an improved endless conveyer adapted to be supported adjacent an inclined track and so arranged with relation-to the track as to be engaged by the supporting hangers which move upon the track so as to retard their descent.

A further object is' to provide improved means for automatically. feeding the hangers to the conveyer.

A further object is to provide an improved device of this character, which Will be simple, cheap and durable in construction, and eflicient and effective in operation.

To the attainment of these ends and the accomplishment of other new and useful ob the features of novelty in the construction,

' combination and arrangement of the several parts hereinafter more fully described and claimed and shown in the accompanying drawings, illustrating an exemplification of the invention, and in which a Figure 1 is a side elevation of an improved conveyer constructed in accordance with the principles of this invention. Fig. 2 is a sectional view, partly in elevation, showing the relation of the hanger upon the supporting track, the guide for the hanger, theconveyer and the guides for the conveyer. Fig. 3 1s a detail side elevation of the conveyer and the hanger showing the relation of the two when inoperative position. Fig. 4 is a detail elevation of the automatic feeding device. A Fig.

5 is a detail plan view of theconveyer pro er.

Fig. 6 is an enlarged elevation of one en of ings and in this exemplification of the invention, the numeral 10 designates one section of an overhead supportin track, and 11 designates another section, w%iich is spacedfrom and arranged below the section 10, such, for example, as being arranged u on'a lower floor of a building. Disposed etween and arranged to connect the sections 10 and '11 is an inclined track section 12, which is supported in any desired manner preferably by means of spaced brackets 13, shownmore clearlyifi Fig. 7 of the drawings. This track section 12 is so arranged that the extremities thereof will stand respectively in line with the

track sections

10 and 11 to form a continuation thereof. The brackets 13 may themselves be supported by suitable beams 14. The brackets 13 are preferably rovided with offset portions 15 on one si e of the track 12 and a similar ofl'set portion 16 on the other side of the track section 12, as shown more clearly in 7 of the drawings. These brackets are also provided with an open space 17 adjacent the track section 12 and arranged adjacent said space and supported by the brackets'is a guide track 18, which is spaced from the track section 12 and so arranged with relation thereto that the u er edge of the guide track will be dis:

pose elow the upper edge of the track section 12 so that the guide track 18 will be arranged to one side of the-track section 12 so as not to interfere with the movementof the hanger upon the track section 12. Arranged on each side of the track section 12 and supported Within the offset ortions 15 and 16.0f the brackets 13, are c annel members or guides 19,'so arranged that the open sides thereof will be dis osed toward the track section 12 and space therefrom and said channel members may be secured in position in any desired or suitable manner, preferably b means of screws .or bolts 20, passing throug a portion of thebrackets.13 and the channel members 19.

Arranged adjacent each end of the chan .nel members 19 is a sprocket wheel 21 and channel members 19 and are supported in suitable bearings upon the beams 14.

The links 26 of the belts 22 are provided with bearings 27 intermediate the pulley wheels 24,.and journaled on these bearings 27 are the extremities of-an axle 28, which are so arranged as to extend across the space formed between the two endless chains and said axle is held from displacement in any desired or suitable manner, preferably by means of nuts 29, which engage threaded portions 30 on said axles preferably between the links of the respective chains, as shown more. clearly-in Fig. 5 of the drawings. These axles 28 and supporting links 26 are arranged at intervals throughout the lengths of the endless chains,

and supported by each axle 28 and disposed between the chains is a wheel or pulley 31, which is provided with a grooved periphery 32 so located as to stand directly above the upper edge of the track section 12. This groove is of such a de th that the bottom 33 thereof will be space above the upper edge of the track section 12, so that the pulley or wheel 31 will be held aloof from the track section. The pulley or wheel 31 is also of such awidth as to substantially fill the space between the extremities of the bearings 27 between the chains so as to prevent the said pulley or wheel from moving longitudinally u on the axle 28, as shown more clearly in Figs. 5 and 7 of the drawings.

When in position, the chains or belts are arranged on each side of the track section 12 and in such position that the pulleys 24 will travel within the channel members 19 and motion may be transmitted to the endless belts in any desired or suitable manner, such as by means of a power belt 34, which may be geared up to one of the sprocket wheels 21 by means of an intermediate shaft 35, as shown more clearly in Fig. 1 of the drawings.

A suitable grooved pulley wheel 36 is adapted to rest and move upon the track section 12 and supported by said pulley wheel 36 is a suitable hanger 37, and said hanger is so constructed that one side thereof will extend below the track section 12 and project through the space formed between the track section 12 and the guide track 18 and terminate in a laterally projecting portion 38 below the guide track 16 and extending beneath the track section 12 so that when an article, such as a beef, is suspended by the hanger, the center of gravity thereof will be below the supporting track section.

In operation the endless belts will move in the direction indicated by the arrow in Fig. 1 and the hangers 37 will be fed from the track section 10 to the inclined track section 12. As the belts are moved, the pulleys or wheels 31 will be brought adjacent the track section 12 and will extend across said track in the path of movement of the hangers 37, so that when the hangers are fed, one at a time, from the track section 10 to the inclined track section 12, the pulley wheel 36 of the hanger will engage and rest against the adjacent pulley wheel 31 supported by the endless belts. When the hangers are on the in clined sect ion 12, they will tend to move along said section under the influence of gravity. but will be retarded in their movement by the movement of the endless belts, the pulley wheel 36 engaging the base 33 of the peripheral groove 32 of the wheels or pulleys 31, will tend to reduce the friction and the flanges of the pulleys or wheels 31 formed by the groove 32 will prevent lateral displacement of the hangers while the guide track 18 between which and the track section 12 a portion of the hanger 37 projects will prevent the hanger from being axially rotated under the influence of the rotary movement which the swinging movement of the heavy weight supported thereby would tend to impart thereto. When the hanger reaches the lower extremity of the track section 12, the engaging pulley or wheel 31 will pass out of engagement therewith, up over the adjacent sprocket wheels 21, and the hanger may be moved in any desired manner and to a suitable place upon the track section 11. It will thus be seen that the hangers may be conveniently fed from an upper to a lower story of a building. The pulleys or wheels 31 are suitably s aced from each other throughout the lengt is of the endless belts so that when two or more hangers are moving upon the track section 12, the hangers or the loads supported thereby will not interfere or contact with each other.

Any suitable means may be provided for automatically feeding the hangers from the track section 10 to the track section 12 and a simple and ellicient means for accomplishing this purpose comprises aswitch or stop designated generally by the reference numeral 39, which is pivotally supported by means of a suitable shaft 40 at the junction of the

track sections

10 and 12. This switch or stop 39 is provided with

enlarged extremities

41, 42, of such a size that the

ed cs

43, 44, thereof will be disposed at an ang e to each other, as shown more clearly in Figs. 1 and 9 of the drawings. The adjacent ends of the the stop or switch to be tracksections 10 and 12 may be connected in any desired or suitable manner, such as by means of a connecting bar or member 45, which extends acrossthe s ace formed between the adjacent ends 0 the

sections

10 and 12 within which the switch or dog 39 is located and the'edge of said bar or member 45 is preferably located below the edge

of'the track sections

10 and 12 so as to be in such a position that the pulley 36 on the hangers 37 will not engage said member.

Inthe resent exemplification of the invention, t e track section 10 is preferably arranged on a slight inclination, as shown more clearly in Fig. 4 of the drawings and in the normal position'of the switch or stop 39 the edge'43 will be in line with and form a continuation of the u per edge of the track section 10 and the e ge 44 will be disposed above the edge of the track section 10, so that when a hanger is moved upon the track section 10 and with the switch or stop in its normal position, the pulley 36 will ride upon the face 43 of the stop or switch 39 and will be retarded in its forward movement by the inclined face 44, as shown in full lines in Fig. 4 of the drawings. When the stop or switch 39 is moved about its axle to the osition, as shown in dotted lines in- Fig. 4, t e inclined face 44 will be lowered into the same plane as the upper ed e of the track section 10, which will permit the hanger supported thereon to advance into such aposition as to enga e the approaching ulley wheel 31 on the ower run of the en es's conveyer, at the same time.

the edge 43 will be raised to the dotted position as shown in 4, causing the end 41 of the switch or stop.39 to assume a position in the path of movement of the next advancing hanger to form a stop therefor and will hold said hanger in such position until the stop or switch 39is moved back into its normal positionto permit the hanger to advance upon eld in such position by the'inclined face 44. j

Any suitable means may be provided for automatically rocking the stop or switch 39 and a suitable and efficient means for accomplisliing this purpose will now be described. Depending from the shaft 40 is an arm 46.

J ournaled in suitable bearings mounted upon a suitable support preferably above the stop or switch 39 is a shaft 47 and depending from said shaft is an arm 48, which is connected to the arm 46 in any desired or suitable manner, preferably by means of an adjustable connecting rod or bar 49, preferably of the turn buckle construction. The shaft 47 is preferably located adjacent the path of movement of the lower runs ofthe endless belts and projecting from said shaft 47 is an arm 50,

the extremity of which is disposed within the path of movement of the pulleys or Wheels 31, so that as the belts are moved, the advancing wheel or pulley 31 adjacent the I extremity of the -50 will engage and de presssaid arm to rock the shaft 47 and through the medium of the arm 48, the connecting bar 49 and the arm 46 will rock the shaft 40 and also the switch or dog 39. The pulleys or wheels 31 which are supported by the endless conveyers are so spaced from each other that when oneof the pulleys is in engagement with the extremity of the arm 50 another pulley will be adjacent the track section 12 and in such a position as to be engaged by the hanger just as it is released by means of the switch or stop..

If desired, an additional arm 51 may be provided on the shaft 40 and upon which is mounted a suitable weight 52 so as to return the switch or stop 39 to its normal position when the Wheel or pulley 31 has passed out of engagement with the extremity of the arm 50.
